Draw 4 icons 20x20 pixels.

It will be easier for those who have dealt with electronic currency exchangers and made exchanges in them to cope with the task.

For this page of the site http://kurses.com.ua/from-perfect-money-usd-to-yandex-money-rub, you need to draw 4 icons. The style and color of the icons should not stand out from the style and color of the site. The size of the icons is 20x20 pixels. The icons will be placed in the rows of the table, next to this 

The icon should not be three-dimensional, but a slightly noticeable shadow can be added. It can even be similar to the one mentioned above. The icon should not have a background or overlay. Only what is specified in the description should be depicted.

The icons should be as follows:

• The first icon should depict a sign of manual exchange. When in the exchanger, the exchange does not happen instantly, but with the participation of the site operator. There is no need to draw a hand. A gear or something similar in meaning will do.
• The second icon should depict the presence of some important information that would require hovering over this icon to see. Something similar to a cloud, like in comics where text was placed, or something similar in meaning will do.
• The third icon should warn that in order to make an exchange, it is necessary to first undergo verification (identification). For example, to present a photo of a passport or payment card.
• The fourth icon should inform that in order to make an exchange, it is necessary to first log in (register) on the site. There is no need to draw a front door. A key to a lock or something similar in meaning will do.
